* core: add derive * fix: fix errors with set! Notably, don't type check dynamic bindings (which can be set to whatever) and eliminate a hang that resulted from not handling an error at the end of the `set!` call. Also refactors some of the code in efforts to make it a bit cleaner. Also adds an error when `set!` can't find the variable one calls set! on. * feat: better derive * test: add error test for derive * document derive * add derive to core documentation to generate * core: add derive * fix: fix errors with set!
